Flights

Though there has been little discussion here I would like to raise an interesting question put to me last week elsewhere on Wikipedia. First, there is currently a geo-centic bias that all space flights begin and end on Earth. Clearly this will not and cannot be the case in the long term when flights are initiated from other established bases or colonies. It has been argued (not orginally be me) that the Moon missions involved two flights as they contained two landings and two launches. But it was put to me that a flight to a space station and then a return on a different space craft many months later is two flights. (Though does it necessarily need to be a different craft?) I raise the question here, because of the Soyuz T-15 mission. The same logic would suggest there were 4 flights in this mission. (1) Launch and docking with Mir, 50 day stay on Mir); (2) trip Mir to Salyut 7, 56 day stay (trip took 29 hours) (3) trip Salut 7 to Mir, 20 day stay (trip took 29 hours) (4) trip Mir to Earth. Is there an official definition. Is there a distinction to be made between, "mission", flights", "trips". NASA only records the mission from and to the Earth in their biographies. Comments.

The page states it was the 10th space station. Surely it's the 8th since all four Skylab operations were done on a single space station and Russians had Skylab 1 to 6? What is the point of counting Skylab multiple times (or, counting the failed Soviet stations when they even failed to reach the orbit and be operational)? 89.168.222.38 (talk) 23:14, 2 March 2015 (UTC)[reply]

Dear colleagues! The reference on David S. F. Portree article is no longer valid (url, I mean). I found this (https://spaceflight.nasa.gov/history/shuttle-mir/references/documents/mirheritage.pdf), but I'm not sure, if it's the original referenced material. Any comments would be welcome!
